usb: typec: anx7411: fix OF node reference leaks in anx7411_typec_switch_probe()

The refcounts of the OF nodes obtained by of_get_child_by_name() calls
in anx7411_typec_switch_probe() are not decremented. Replace them with
device_get_named_child_node() calls and store the return values to the
newly created fwnode_handle fields in anx7411_data, and call
fwnode_handle_put() on them in the error path and in the unregister
functions.
